lightly stuffed with gauze or cotton wool, a drain inserted, the wound 

 sutured, and the animal allowed to rise. 



In twenty-four hours the sutures may be loosened and the wound 

 rinsed out with sublimate solution. Dressing with iodoform and 

 tannin is persevered with. To prevent interference with the wound, 

 the animal should be placed on the pillar reins, or a side-stick applied 

 in the recognised manner. After a few days a dry black scab covers 

 the surface of the wound, and, if it become loose in spots, should 

 be removed and the antiseptic powder reapplied. Towards the 

 edges of the wound a small quantity of discharge may appear, which 

 can be removed with cotton wool and the surface again powdered 

 with iodoform and tannin. During the first six days the wound 

 shows no marked change under this treatment, but gradually becomes 

 smaller, and in about three or four weeks the cavity will have com- 

 pletely filled up. 



An abscess of the shoulder, extirpated on July 16th, left behind a 

 cavity 7 inches long, 4 inches broad, and 2£ inches deep. Until the 22nd 

 no marked change had occurred, but subsequently the dimensions were 

 reduced as follows : — 



In such cases open wound treatment is not only the quickest, 

 but the most convenient. When a dry scab is produced over the 

 entire wound nothing further is necessary. 



VI.— SADDLE AND COLLAR GALLS INJURIES FROM PRESSURE— 

 FISTULOUS WITHERS. 



The saddle and collar exercise heavy pressure on the tissues 

 below, and may produce injuries to the skin or subjacent textures. 

 These are usually of the nature of bruises, seldom of excoriations ; 

 and as those produced by the saddle possess the greater interest, 

 they will be first considered.

To prevent the pressure of the saddle injuring the back, the
